Baden-Powell took the first steps in the training of Scouters by organizing a series of lectures for Scouters in 1911. He made great strides by devising and instituting Wood Badge Training in 1919. Wood Badge recipients now number more than 100,000 throughout the world. The object of the Wood Badge course is to demonstrate, as practically as possible, the aims and methods of Scouting. Upon successful completion of the course the participant receives a certificate and the Wood Badge - two wooden beads worn on a leather thong around the neck. These beads replicate the beads found by Baden-Powell during a campaign in Africa in 1888. They belonged to Dinizulu, an African chieftain. In searching for a suitable recognition for those who completed the first course in 1919, Baden-Powell remembered the beads and decided to present a bead to each participant. At that time, the course was called Wood Badge. The Wood Badge may be worn only with the official field uniform of the BSA. The Scouter to whom it has been awarded may also wear the tan neckerchief with its patch of MacLaren tartan at the back. The Wood Badge neckerchief may only be worn with the accompanying leather neckerchief slide or woggle.​
